I just wanted to get some opinions on my closed loop plan. The tank is a 75g and I plan to drill it as follows. The larger 3 holes are 2 5/8" for 1 1/2" sch 80 bulkheads and the 4 smaller holes are 1 7/8" for 1" sch 80 bulkheads. The larger center hole is for the overflow that will be placed in the tank. The other two large holes are for the closed loop intake and the 4 smaller ones are for the closed loop outlets. And honestly, my main concern is, too many holes for the glass? The glass appears to be 1/4" thick which I assume is standard on that size tank. What do you think?
Oh and the red lines are spaced 3" except for the space between the first one and second one from the top. Dimension wasn't a multiple of 3.
